Is the media creation tool kept current?

I can't get the anti-freezing update (kb) on 10 au on a fresh install before it crashes.
Additionally, the updates I do get all fail.
I am making another copy of the media creation tool with the hopes that somebody (anybody) was smart enough to include updates and fixes in the image download.

I want to know if I am expecting too much- am I just making a copy of AU-RTM from a month ago?
